Common name: Tickseed - the seeds are shaped like a tick.
Unsung stalwarts of the border that flower for ages is deadheaded. They like a sunny spot and soil that isn't boggy. The verticillata types will grow in dry soils quite happily. Deadheading is essential and I find that a quick clip all over does the job. This results in no flower for a couple of weeks but is easier for a busy gardener than cutting each off individually.
The verticillatas are long-lived and spread quite slowly to form small clumps and can be propagated by division.
Coreopsis are members of the Asteraceae family.
